Where to find out for the CATALOG.Item component parameters and settings? The whole google was missing there is nothing about him at all.

No matter how the components have a .parameters.php file

this does not have it. But in the class it is clearly written that the parameters are accepted all.

In essence, this is a dummy in which standard parameters are transmitted to the parameters and all that the head will take up but in the component class there is an instruction that spins in Arresult property ‘result’ from the parameters
